How about the wifi module on SDIO? This will be nice addition and wills save one USB host. I know that this is possible and (some) wifi chips supports SDIO interface. But I think that all chinese tablets are using USB modules? Tsvetan has uploaded spec for one of usb module on his github and it is USB interface. Anybody knows if SDIO modules are much different in price?<div>
I checked and saw that Realtek chips (RTL8188, 8191, 8192) are USB only. Ralink (Mediatek) too. So it depends on the price difference on moving from USB to SDIO based one (SDIO mode support for A10 in linux kernel?).<br><br>

</div> there are three (one of which is USB-OTG). one goes out on the A10<br>
EOMA-68's 68-pin interface, the USB-OTG on the front connector and the<br>
last one is on the 44-pin expansion header.<br>

</div> the SD 3.0 wifi interface(s), one of which is on the A10 CPU card's<br>
44-pin expansion header.<br>

</div> that's why one was chosen for the A10 EOMA-68 CPU card.<br>

</div> it may turn out to be highly price-performance and<br>
performance-per-watt competitive.<br>
<br>
also, this is why the plans are to do this as a modular design, so<br>
that the CPU cards can be replaced as-and-when. i upgraded the<br>
EOMA-68 interface (and the EOMA-CF one) to Gigabit Ethernet, just for<br>
the purposes of allowing 10/100/1000 Ethernet for when CPU cards with<br>
gigabit ethernet are available.<br>
